I have dull pain left chest , shoulder, jaw, neck and ear. Comes and goes. Had an EKG done 3 months ago and everything looked fine. I cant tell if it come with movement or breathing . Sometime all 5 hurt at the same time ,sometimes just one or the other. I hear a pulse like sound in right ear, ALL the time. Blood pressure is slightly high. I smoke about 10 cigs a day. I've had this issue for a while now. Sometimes I feel like it is heart related and sometimes I feel it might me muscle related. I have no clue.....
